BOTTLE.

SPECIFICATION forming part of Letters Patent No. 320,751, dated June 23, 188,5.

Application filed March 31, 1885. (No model.)

T0 all whom, it may concern:

Be it known that I, THEoDoR BERGMANN, of the city of Gaggenau, in the Grand Duchy of Baden and German Empire, have invented a certain new and useful Improvement in Siphons, of which the following is a specification, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to siphon-bottles for aerated or gaseous liquids; and it consists'in the novel combination of devices hereinafter described and claimed,rcference being made to the accompanying drawings, in which- Figure 1 is a vertical transverse section of the improved apparatus, the bottle being closed. Fig. 2 is a front View of the apparatus open, and Fig. 3 a similar View of the apparatus closed. Fig. 4 is a toprview of the apparatus, and Fig. 5 is a horizontal transverse section of the same on the line A B, Fig. 2.

Like letters of reference indicate similar parts throughout the drawings.

a indicates a bottle having a centrallyperforated plate, b, placed upon a shoulder formed on the upper inner ange of the said bottle. The plate has fixed to its underside a pipe or tube, c, and to its upper side a funnel-shaped pipe, d, communicating with the pipe @through the said central opening in the plate b, or forming a continuation of the said pipe c. The upper flange of the said funnel-shaped pipe is covered with an annular piece of indiarubber or other suitable packing material.

e is the bell-shaped siphon-head, pivoted at g to the ringf around the neck of the bottle a, the interior part of the head e being of such shape that when closed it will bear or press upon the upper india-rubber-covered lange of the funnel d, and thus form a hermetically-closed joint between the upper part of the head e and the pipe c.

Instead of connecting the head to the bottle as hereinbefore described, it may be attached thereto in any other suitable manner. To the said upper part of the head e are applied, in the usual manner, well known in the construction of Siphon-bottles, the outflow-pipe top, and arranged upon the pipe c so that it may slide thereon.

The operation of the improved apparatus when it is to be applied for producing aerated drinks is as follows-that is to say, after having pressed down the handle 0 the head e is thrown back, and a liquid, such as still wine, water, or the like, is poured into the bottle a, so as to iill about three-fourths thereof. The receptacle p is then moved by hand near to the upper end of the pipe c, and filled with the proper amount of some suitable substance for producing carbonio acid-for instance, with such as has been referred to hereinbefore-whereupon the head e is brought down upon its seat and locked in position again, thus establishing the proper and hermeticallysealed connection between the several working parts of the apparatus. The receptacle p, with the said efervescent substances arranged therein, will then be above the level of the liquid within the bott-le a, and will rcmain so until it is desired to prepare and use the aerated drink. rlhe bottle is then turned upside down or shaken, so as to bring thesaid substances in contact with the liquid, and to cause thereby the aeration of the latter. The pressure of the carbonio acid thus produced will, on pressingthc handle z', force the aerated drink from the bottle, all this being well understood and requiring no further description. The pressure exerted by the carbonio acid having emptied the bottle of its contents, the head c is opened, whereupon the bottle may be readily cleaned and replenished, and the operation repeated as described.

lt will be seen that with a siphon constructed as herein described there can be no loss of carbonio acid, the latter being produced only after all parts are hermetically closed and when the drink is desired to be consumed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a Siphon-bottle having a shouldered mouth, of a Siphon-head, c, a plate, b, seated on the shouldered mouth of the bottle, the tube c, xed to the under side of the plate7 and the funnel-shaped pipe d, fixed to the upper side of the plate and communicating with the tube through the said plate, substantially as described.

2. In a siphon bottle or apparatus for producing aerated drinks, the combination, With the removable head e, having an inner ange iitting hermetically upon the pipe (l, and a lower flange fitting hermetically upon the bottle a, of the pipe d, the plate I), and the pipe c, substantially as and for the purpose speciiied.

3. The combination of the Siphon-bottle, the plate o, seated at the upper end thereof, the tube c, depending from the under side of the plate, the pipe d, rising from the upper side of the plate and having a flanged upper end covered with rubber, and the siphonhead e, hinged to the bottle and adapted to bear against the flanged end of the pipe, substantially as described.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

THEODOR BERGMANN.
